I have custom method in my store (I used \Magento\Payment\Model\Method\AbstractMethod class). In the isAvailable method, I get a string that I would like to display to the customer at the checkout. Now, the checkout looks like this:

enter image description here

But I would like to be able to display additional message here, like this:

enter image description here

The additional string is constructed in isAvailable, so all I need is to pass it to method-renderer.js or checkout_index_index.xml (I think).

I can also construct the string in custom controller, so I was thinking of adding some JS to checkout that will hit custom controller with HTTP GET request and then add it to the source, but I hope there is a better way to do it.

  • you need to add additional string on checkout page right ? – Yogesh Nov 13 '17 at 10:30
  • @Yogesh yes, I need to display string when choosing payment option. But this string is different every time. – Adam Ježek Nov 13 '17 at 14:21

I have posted basic code for passing data to checkout payment form which you can modified as per your requirement. create SampleConfigProvider.php under File path :-



 namespace Namespace\Modulename\Model;

 use Magento\Checkout\Model\ConfigProviderInterface;

   * Class SampleConfigProvider

 class SampleConfigProvider implements ConfigProviderInterface

   public function getStoredCards(){
      $result = "This is your string";
      return $result;

   public function getConfig()

     $config = array_merge_recursive($config, [
       'payment' => [
          \Namespace\Modulename\Model\Payment::CODE => [
            'storedCards' => $this->getStoredCards(),
   return $config;

Then add CompositeConfigProvider in frontend/di.xml

File Namespace/Modulename/etc/frontend/di.xml

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<type name="Magento\Payment\Model\CcGenericConfigProvider">
    <argument name="methodCodes" xsi:type="array">
        <item name="test_payment" xsi:type="const">Namespace\Modulename\Model\Payment::CODE</item>
<type name="Magento\Checkout\Model\CompositeConfigProvider">
    <argument name="configProviders" xsi:type="array">
        <item name="test_payment_config_provider" xsi:type="object">Namespace\Modulename\Model\SampleConfigProvider</item>

add code in your js file which are present in give path (Namespace/Modulename/view/frontend/web/js/view/payment/method-renderer) :

   getStoreCard: function() {
        return  window.checkoutConfig.payment.PAYMENTMETHODCODE.storedCards;

Now you can get this string your html file which is located on (Namespace/Modulename/view/frontend/web/template/payment)

<span><!-- ko i18n: getStoreCard() --><!-- /ko --></span>

You can adjust location of code based on where you want to display,You can take a reference this answer & this blog .

You should not add string in isAvailable method because when you check in parent class its return boolean value
